LOOM.

SPECIFICATION forming part of Letters Batent N 0. 708,251, dated September 2, 1902.

Application filed November 14, 1901. Serial No. 82,238. (No modeLl To all whom it may concern:

Be it known that LOSCARL. OWEN,a citizen of the United States, residing at Whitinsville, in the county of Worcester and State of Massachusetts, have invented a new and useful Improvement in Looms, of which the following is a specification.

This invention relates more particularly to the part of the loom mechanism by which the cloth-roll is supported and held against the take-up or sand roll.

The principal object of the invention is to provide means for controlling the support,and thereby facilitate the insertion and the removal of the cloth-roll. To this end I have devised a support for the journals of the clothroll in which coiled springs inclosed in telescopic tubes form the yielding supports of the cloth-roll, and cords connected with the journal-supports and with a winding-drum control the actions of the coiled springs, whereby the cloth-roll may be lowered to release the pressure of the cloth-roll against the take-up roll to facilitate the removal of the same or acloth-roll placed on the journal bearings and raised under the control of the operator against the take-up roll.

The particular novel features of my invention will be more fully described hereinafter and more particularly pointed out in the claims.

Figure 1 is a front elevation of parts of a loom, illustrating my invention. Central por tions are shown cut out to reduce the width of the drawing. Fig. 2 is a 'transverse sectional view of the front part of a loom provided with my improvement. Fig. 3 is an enlarged view, partly in section, of a detail, showing the connection of the cord with the winding-drum. Fig. L is a sectional View of a detail, showing the worm and worm-gear for operating the winding-drums.

Similar marks of reference indicate corresponding parts in all the figures.

'In the drawings, 1 indicates the end frames of the loom; 2, the breast-beam; 3, the lower front strut; 4., the friction-roll; 5, the takeup or sand roll; 6, the path of the cloth over the breast-beam, the friction=roll 4, and the take-up roll 5'of the cloth-roll 7. The journals on the opposite ends of the cloth-roll are supported on the'journal-bearings 8, secured in the upper end of the tube 9, which tube telescopes with and slides in the tubelO. The bottom ends of the tubes 10 are perforated. The coiled spring 11 extends from end to end of the two telescopic tubes 9 and 10 and; bears against the closed ends of the tubes to force the tube 9 outward from the tube 10. The cord 12 has one end secured to the journalbearing 8. The cord extends through the central space inclosed by the coiled spring 11, through the opening in the bottom of the tube 10, and onto one of the sheaves 13. The two sheaves 13 13 are secured to the shaft 14, on which the Worm-gear 15 is secured. The worm 17 engages with the worm-gear 15 and is secured to the crank-shaft 16, supported in suitable bearings. By this construction the cord 12 may be partially wound on the sheave 13 and the tube 9 drawn into the tube 10 against the force exerted by the coiled spring 11. As there are two such spring-supports for the cloth-roll, one for each journal, and as the sheaves 13 13 are on the same shaft, the r0- tation of the shaft 1% by the worm 17 and wormgear 15 controls the position ofboth the journal-bearings 8 8 and of the cloth-roll.

In the preferred construction the tube 10 is formed integral with the arm 18 and with the base 19. The arm 18 is rigidly secured to the breast-beam 2, and the base 19 to the strut 3, the friction-roll 4 being preferably supported in the arm 18. The strain exerted by the springs 1111 through the cloth-roll on the take up roll is resisted by the structures forming the cloth-roll, which is secured to the breast-beam and the front strut some distance from the end frames and imparts strength and rigidity to the loom.

As the cloth is wound upon the cloth-r0117 the diameter increases and the tubes 9 9 are gradually pushed into the tubes 10 10 against the action of the springs 11 11, the cords 12 12 becoming slack until the desired amount of cloth is wound upon'the'roll 7 and the same is to be removed, when upon turning the crank-shaft 16 in onedirection the shaft 14: is revolved, and with itthe sheaves 1313, to take up the slack of the cords-12 12 and also sufliciently to lower the cloth-r0117, so that the same may be readily removed from the bearings 8 8 and another roll substituted therefor. The crank-shaft is then turned in the opposite direction to unwind the cords 12 12 from the sheaves, which causes the springs 11 11 to lift the cloth-roll to the desired position for the rewinding of the cloth thereon.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a loom,1he combination with the clothroll, and the telescopic spring-actuated supports of the same, of a winding-shaft, sheaves on the same, cords connected with the clothroll supports and with the sheaves on the winding-shaft, and means,comprising a worm and worm-shaft, for operating the windingshaft, as described.

2. A journal-support for the cloth-roll of a loom consisting of two tubular chambers, a tube sliding longitudinally in each tubular chamber, journal-supports on the free ends of the sliding tubes, coiled springs bearing on the bottom of the tubular chambers and the journal-supports on the sliding tubes, and cords connected with the sliding tubes and with a winding device, as described.

3. In the loom, the combination with the breast-beam, the front strut, the take-up roll, and the cloth-roll, of vertical struts secured to the breast-beam and the front strut, a tubular chamber forming part of each strut, tubes telescopically supported in the tubular chambers, journals bearing on the free ends of the tubes, a winding mechanism below the tubular chambers, and cords connected with the winding mechanism and the sliding tubes, as described.

4. In a 100m, the combination with the breast-beam, the take-up roll, the frictionroll, and the cloth-roll, of the arm 18, the tube 10, and the base 19 formed integral and secured to the breastrbeam and the front strut, the tube 9, the journal-bearing 8 on the same, the cord 12 connected with the journal-bearing and with the winding-sheave 13, and mechanism for operating the two windingsheaves of two journal-bearings simultaneously and comprising a worm and worm-gear, as described.

In testimony whereof I have signed my name to this specification in the presence 01 two subscribing witnesses.

OSCAR L. OWEN.
